Abstract
We examined five annual cohorts (2007–2011) of men who have sex with men (MSM) attending New York City STD clinics who had negative HIV-1 nucleic acid amplification tests (NAATs) on the day of clinic visit. Annual HIV incidence was calculated using HIV diagnoses within 1 year of negative NAAT, determined by matching with the citywide HIV registry. Predictors (demographic; behavioral; bacterial STD from citywide STD registry match) of all new HIV diagnoses through 2012 were calculated from Cox proportional hazards models. Among 10,487 HIV NAAT-negative MSM, 371 had an HIV diagnosis within 1 year. Annual incidence was 2.4/100 person-years, and highest among non-Hispanic black MSM (4.1/100 person-years) and MSM aged <20 years (5.7/100 person-years). Characteristics associated with all 648 new HIV diagnoses included: black race (aHR 2.2; 95 % CI 1.6–3.1), condomless receptive anal sex (aHR 2.1; 95 % CI 1.5–2.8), condomless insertive anal sex (aHR 1.3; 95 % CI 1.1–1.8), and incident STD diagnosis (aHR 1.6; 95 % CI 1.3–1.9). MSM attending STD clinics have substantial HIV incidence and report risk behaviors that are highly associated with HIV acquisition. Increased uptake of effective interventions, e.g., pre- and post-exposure prophylaxis, is needed.
